PLUMB-BOB.

SPECIFICATION forming part of Letters Patent No. 266,671, dated October31, 1882.

Application filed June 30, 1882.

To all whom it may concern Be it known that 1,W1LLIAM L. BERGEN, acitizen of the United States, residing at Batavia, in the county of Kaneand State of Illinois, have invented a new and useful Improvement inPlumb-Bobs, of which the following is a specification.

My invention consists in the combination of a case to protect the pointof a plumb-bob from injury with a spool on which to wind the line usedwith the same. The method of construction by which this result isaccomplished will be readily seen by reference to the accompanyingdrawings, in which 7 Figure 1 represents a side View; Fig. 2, a sectionthrough the axis on the line n 0, Fig. 8; and Fig. 3, a top view.

A, Figs. 1, 2, and 3, is a metallic plumb-bob of ordinary design.

B, Figs. 1, 2 and 3, is a combined case and spool having a hole or boreof the same size and shape as the conical portion of the plumbbob A, thehole being slightly larger 3. short distance inside of the opening, soas to corre- (No model.)

spond to the contour of the plumb-bob A from its point to a shortdistance beyond its greatest diameter. The case B is also provided withseveral longitudinal slits, a, Figs. 1 and 3, cut to a depth sufficientto allow the mouth of the hole to expand enough to allow the greatestdiameter of the plumb-bob A to pass through the opening, after which thesides of the case will spring to their original position, and thusprevent the plumb-bob from dropping out of the case too easily, while itmay readily be pulled out when required. also have a wide groove out inthe lower portion of its outer surface, as shown at 9, Figs. 1 and 2, inwhich the line may be coiled when the plumb-bob is not in use.

What I claim as new in the foregoing is The combination of the plumb-bobA with the case and spool B, substantially as and for the purpose hereindescribed and shown.
